[lttng-tools 0/2] Fix various polling loops when using poll()

[Philippe Proulx]

When disabling epoll (--disable-epoll), poll() is used instead of
epoll_wait() thanks to the compat layer. While epoll_wait() only returns
the file descriptors that are ready, with poll() you need to check all
file descriptors and process only those which have revents flags.

This patchset fixes a few of those polling loops in LTTng-tools where
it is assumed that revents is not 0 (epoll_wait() behaviour).

Philippe Proulx (2):
  Fix: sessiond: revents may be 0 when using poll()
  Fix: relayd: revents may be 0 when using poll()
